ABSTRACT
Trichinosis was experimentally induced in rats. The morphology of encystation of Trichinella larvae was studied in the striated muscles. The efficacy of albendazole was evaluated in different intensity of Trichinella larvae infestation in the striated muscles of the laboratory animals. Encystation was shown to cease at 21 days. Albendazole showed high activity against intestinal and encapsulated larvae of Trichinella, leading to 100% death of T. spiralis. Capsules and Trichinella larvae were described to be destructed after treatment with albendazole 15 mg/kg twice daily for 10 days.

The authors propose a mathematical model that makes it possible to estimate the severity of experimental trichinosis from the peripheral blood values of a laboratory animal (white blood cells, neutrophils, eosinophils, and lymphocyates).

The introduction of a novel entomopathogenis nematode Steinernema carpocapsae strain "agriotos" (Rhabditida: Steinernematidae) into the soil of an orchard resulted in the reduction (up to 50 %) of total amount of phytophagous insects. No negative effect on the groups of beneficial arthropods, caused by the nematode, has been found. Recommended optimal application rate is 500 thousand invasive nematode larvae per 1 m2 of the soil. Increase or decrease of the application rate resulted in the rise of the abundance of phytophagous insects. This fact proved the existence of regulating factors determining optimal ratios of the amounts of parasites at micro- and macro-levels. Activation of native populations of entomopathogenic nematodes in soil surface layer has been observed after the introduction of the novel parasite species.
